COS Frequently Asked question (FAQs)

How can I get a COS Promo Code in Hong Kong?

You can find verified COS Promo Code listings on MyCouponCodes.hk. COS also shares limited offers via newsletter, app notifications, and seasonal campaign pages. Check before checkout for the best live code.

Does COS offer a first order discount in Hong Kong?

COS sometimes runs a new customer perk via newsletter sign-up or limited campaigns. Availability changes by region and period, so look for a COS Discount Code banner or welcome email at the time you shop.

Can I combine multiple COS coupon codes in one order?

No, COS generally allows only one promo code per order. You can, however, stack codes with sitewide sales or free shipping promotions if available.

Where do I enter my COS Promo Code at checkout?

On the payment or review page, look for a field labeled Discount Code or Promo Code. Paste the COS Promo Code, click Apply, and confirm the price updates before you place the order.

Can I use a COS Promo Code on sale items?

Often, COS Discount Codes apply to full-price products only. Sale, outlet, collaborations, or limited capsules may be excluded. Always check the terms printed with each offer.

What are the best times to find a COS Discount Code in Hong Kong?

Peak windows include 11.11 Singles Day, Black Friday, Cyber Monday, Double 12, and festive sales around Lunar New Year. During these periods COS may run automatic markdowns and occasional codes.

Can I stack a COS Promo Code with free shipping or other perks?

Stacking is limited. A COS Discount Code may not combine with other promotions, automatic reductions, or bundle deals. If stacking is allowed, the cart will show it clearly after applying the code.

Do COS Hong Kong orders get free shipping without a code?

Free delivery is sometimes offered during promotions or above a threshold. When active, no code is needed. If a COS Promo Code is applied, shipping terms usually remain unchanged unless stated.

Does COS have student, referral, or birthday discounts in Hong Kong?

These perks may appear during selected campaigns or through partner platforms. They are not guaranteed year-round. Check the current COS Discount Code terms or membership emails for eligibility.

Are COS Promo Codes region specific?

Yes. A COS Promo Code issued for another country usually will not work on the COS Hong Kong site. Use codes specifically marked for Hong Kong or APAC to avoid errors at checkout.

Why is my COS Discount Code not working?

Common reasons: code expired, minimum spend not met, trying to apply on excluded items, or using a non-HK region code. Enter the code exactly as shown and review the offer conditions.

Can I use a COS Promo Code on new arrivals or collaborations?

Many codes exclude new drops, limited collaborations, and selected categories. Check the exclusions list in the COS Discount Code terms before adding items to cart.

Do bank cards or e-wallets offer extra savings with COS?

Banks and wallets in Hong Kong sometimes run limited rebates or cashbacks. These are handled by the payment provider, not COS, and may not stack with a COS Promo Code. Check the payment promo’s terms.

Is there a COS app-only discount for Hong Kong shoppers?

App pushes may include exclusive alerts or early access. When an app-only COS Promo Code is active, the terms will specify App required. Enable notifications to avoid missing short-window deals.

If I return an order placed with a COS Discount Code, how is the refund handled?

Refunds usually reflect what you actually paid after the code. Shipping or handling fees are typically non-refundable unless required by the promotion or local policy. Check the return page before sending items back.

What is the smartest way to maximize savings at COS?

Compare the net result of a COS Promo Code versus sitewide markdowns. As a rule of thumb, bigger carts often benefit more from percentage codes, while automatic sale prices can win when exclusions limit code usage.
